Rivian R1T charging curve test 20-80% [by TFL]

[azbill]

Yes, If I recall one location was an ABB unit and the other was Signet.

The unit in your video was not ABB or Signet, probably a BTC unit. All Signet units are capable of 500A, whether they are 150kW or 350kW. ABB 350kW units are limited to 450A and the ABB 150kW units are limited to 350A.

I have never seen nor used one of the BTC or Efacec units, so I have no idea what those current ratings are.

My personal experience with EA is that if the cable chillers are inoperative, they limit the output to about 35-40kW. This happens a lot with ABB units in hot weather. I have never seen that happen on a Signet unit.

$26.66 for 73Kwh at 1.85 mi/KWh is $0.2 /mile
wife’s outback $0.11 /mile. ($3.26/gal in my neighborhood)

A fairer comparison of cost/mile would be for a 5000+ lb SUV or pickup - not an Outback. Cost per mile will be much closer...

If one does all their charging at a public (expensive) station cost per mile can be fairly high. Most people will be doing the bulk of their charging at home for rates much less than $0.31/KWh. In my situation I will be paying a little over $0.10/KWh when charging from the grid, or free when powered by my rooftop PV array.

Someone said they wish they could spend an extra $5000 for an 800V system. Wouldn't that be signing up for the Max Pack?

Think of it as:
$5000 for 800V, and
$5000 for +100 miles range

If the rumor is correct that Max Packs will get 800V. Anyone know for sure?

This would be awesome, but I haven't seen this anywhere. Hopefully, this is what the delay is for?

The cold weather real world range using luxuries like heater are basically unknown outside of a few subjective reviews. Scant info from ACTUAL owners at this time

Subjunctive reviews? As in reviews that might have happened?

Interesting.

You made my day.

my 1.5 cents: charging to 80% is not the way to do it, especially on road trips. 15-65% is your target. Why? Even in our 2021 Tesla it drops below 100 kWh around 50-60%. It is a waste of your time to sit there after that. Make more stops. 80-85% is for food stops and in charging deserts.

20k miles in 10 months across Montana and the Dakotas for some of our trips and this worked fine. They’ll tinker with the curve, but you’ll be happier if you tinker with your perspective on stops.

I think having solid charging deep into the charging curve is important on trucks that may be towing or have roof racks impacting efficiency

The former Latin student in me couldn't resist, I'm just glad anyone understood it.

You're going to get better or worse charging curves depending on the charger. Some chargers are fast, some are slow. I tend to believe the R1T/S will have an average charging curve similar to what TFL experienced, for all the credit Rivian gets it really is using a now obsolete 400v system.

People expecting fast charging stops are going to be disappointed. A big, inefficient battery + a 400v system is not a combination that enables that.

This isn't a dealbreaker for me, but it is the reality. Software can't suddenly make a 400v system charge faster.

Yes, but a 400V system can charge at over 200kW. The last 25% that Rivian is currently sitting on is significant.

Of the new EV trucks coming to the market, only the Lightning is capped at a slower speed (150kW).

The Silverado, CT, and the Hummer are all faster.

We have a Dual Motor Model Y and we never get max charging on road trips. Going from LA to Las Vegas and using the nav to pre condition, we NEVER get over 140kwh after the first minute or so of charging. Even if the station in Baker is empty. We are usually there for 30 minutes to get enough juice to get us home. Not much different than the R1T results. On a new Supercharger station in Mesquite NV, we did see much higher charge rates for 5 minutes or so, then back to the 150's only to trickle off as we got past 80%.

The curve for the Rivian R1T didn't seem much different.

I can't tell if the answer means it already preconditions so there's no user selectible setting, if they mean preconditioning as a whole doesn't do anything, or if the vehicle is currently incapable of preconditioning. There are varying degrees of bad.

is preconditioning simply making sure the truck is not “cold”.

The bigger the battery pack, the greater the importance of charge rate.

This thread has given some really good experience based charging tips. I’m going to tinker with some of my ABRP “test routes” and see how some of these changes impact my itinerary.

More specifically the battery pack. A warmer pack is a happier pack while charging, up to a certain point. That’s why the response is a bit vague. Preconditioning may not be necessary if you’ve been driving around constantly all day. But in the event you have been stopped for a bit can one trigger preconditioning prior to charging? Several questions still open but it can ultimately be fixed by an OTA.
